We ran a population sampling study to
determine the level of confidence of our
study which revealed, based on 39,183,891
people aged about 15 to 24, that our
sample of 292 had a 95% confidence
interval of plus or minus 5.7% reliability
(precision). Doubling the study sample
to 588 would have a 95% confidence
level of 4% from 5.7%, indicating that
we can be confident that our sample of
292 represents the population at large
